Abstract

Provided is a curable petroleum resin, and a preparation method and a use thereof, the curable petroleum resin comprising a repeating unit derived from a petroleum resin monomer, a repeating unit derived from a silane monomer and a repeating unit derived from a C3-C20 alpha-olefin monomer. The curable petroleum resin is used as an additive in a reactive polyolefin-based adhesive composition to increase the adhesive strength to a polyolefin-based substrate used for various parts.
